If I may interject, wearing my Debian-packager hat: if at all  
possible, please avoid (3).  When the vendor already ships fftw (as I  
expect all linux vendors do), you're exposing the ITK user to (a)  
duplication, and (b) version-skew problems if they naively link an ITK  
project with FFTW as well.

By all means, provide easy-to-use bundles for those who are building  
from source, perhaps including fftw.  But please keep the core ITK  
distribution free of bits easily available elsewhere.

Thanks,
